Hi Dwight, Shaheerah is peer-reviewing my write-up for the draft flare permit and we need the following information available when we are ready to public notice the permit. Hope it works for you if we can get the information from you within a month's timeframe. Also, can you let me know how things are going with the modeled impacts for Hovenweep that Don Shepherd at the National Park Service asked for? Thanks again for your help.

Hi Andrew, Here is the additional info that is needed to fill in some of the gaps for the MCU AAQIR PSD permit amendment. It would be very helpful if you could get this info from Resolute and find out if the company can provide this info within the next month or so. Thanks. 1) Provide facility-wide actual emissions and PTE estimates for SO2,CO, NOX, VOC, PM, PM10. and PM2.5. Section 3 of the 2008 PSD application provides emissions info for the Main Flare only. 2) Provide actual emissions and PTE estimates for SO2, CO, NOX , VOC, PM, PM10. and PM2.5 for the following emission units. Section 3 of the 2008 PSD application provides emissions info for the Main Flare only.
TEG Reboiler (0.33 MMBtu/hr) - Operational  Main Flare (618,104 scf/hr) - Operational  Gasoline Storage Tank (1000 gallons) - Operational  Glycol Heater (rated size/capacity?) - Operational  3) Verify the accuracy of the rated sizes/capacities of the following emission units, and provide the rated sizes/capacities where none is identified.
TEG Reboiler (0.33 MMBtu/hr) - Operational  Main Flare (618,104 scf/hr) - Operational  Gasoline Storage Tank (1000 gallons) - Operational  Glycol Heater (rated size/capacity?) - Operational 4) Verify the accuracy of the following information regarding the operational status of (i) the emissions units listed in the current PSD permit and (ii) the other operations at the MCU facility. Equipment in current MCU Facility PSD Permit lasted amended in 1991: T4500 Gas Turbine (4390 HP) - Shutdown 1997  Waste Heat Recovery Unit (11 MMBtu/hr) - Shutdown 1997  Ingersoll Rand IC Engine (491 HP) - Shutdown 1993  Fairbanks Morse IC Engine (1712 HP) - Shutdown 1997  Fairbanks Morse IC Engine (1712 HP) - Shutdown 1997  Fairbanks Morse IC Engine (1848 HP) - Shutdown 1997  Fairbanks Morse IC Engine (1848 HP) - Shutdown 1997  DPC-540 IC Engine (470 HP) - Shutdown 1998  HC Liquid Reboiler (1 MMBtu/hr) - Shutdown 1993  Heat Medium Heater (4 MMBtu/hr) - Shutdown 1993  Heat Medium Heater (12.2 MMBtu/hr) -Shutdown 1991  TEG Reboiler (0.33 MMBtu/hr) - Operational  TEG Reboiler (0.33 MMBtu/hr) - Shutdown 1991  TEG Reboiler (0.33 MMBtu/hr) - Shutdown 1991  TEG Reboiler (0.1 MMBtu/hr) - Shutdown 1991  Other Operations at the MCU Facility: Natural Gas Liquids Processing - Shutdown 1998  Natural Gas Processing Facility - Shutdown 1998  Main Flare (618,104 scf/hr) - Operational  Gasoline Storage Tank - Shutdown 1993  Gasoline Storage Tank - Shutdown 1993  Gasoline Storage Tank (1000 gallons) - Operational  Diesel Storage Tank - Shutdown 1993  CO2 line heater - Shutdown 2004  Glycol Heater - Operational  5) EPA was provided the attached description of the MCU facility by Mobil in the past. Please verify the accuracy of this information and clarify whether it is acceptable to use this description as part of the PSD application [attachment "MCU Summary.pdf" deleted by Andrew Chew/R9/USEPA/US]
